EXTENSION TABLE.

Application filed April 1;

T 0 all whom it may concern:

Be it known that I, HANS MAHNCKE, a citizen of the United States, residing at Colorado Springs, inthe county of El Paso and State of Colorado, have invented certain new and useful Improvements in Extension Tables, of which the following is a specification. I V

This invention relates to tables of the extensible type.

An important object of this invention is to provide a table having a pair of extensible leaves which may be positioned directly beneath the main top when not in use sothat the extensible leaves will not in any way interfere with a person sitting at the table.

A further object is to provide an extensible table having simple means whereby the extension leaves are securely supported when extended whereby the same are prevented from sagging.

Another object of this invention is to'provide an extension table which is of highly simplified construction, neat in appearance and cheap to manufacture.

Other objects and advantages of-the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective of the improved extension table. I

Figure 2 is a sectional perspective of the same, the view illustrating the bottom of the table or the underside of the'top.

Figure 3 is a bottom plan view of the table. i

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention'the numeral 5 ignates the legs of the table, the said legs being connected at their upper ends'tothe usual side and end cross bars 6 and 6. An

intermediate strip 7- is permanently connected to the end cross bars 6' at the ends of the table by means of L-shaped brackets '8.

'The main top is designated by the numeral 10 and is loosely connected to the intermediate strip 7 by means of'a pair of guide strips 11' secured; to the underside of. the.

F P. by means of fastening devices 12, AS illustrated. i Fi 3 the guide p 11 of which there are two are received in cutaway portions in opposite sides of the stationary strip 7 whereby the top is held against excessive lateral or endwise movement. by the intermediate strip. It will be;

ward movement by means of a cross plate 15 secured to the intermediate portions of the guide strips 11 and extending-beneath longitudinally. Further the top is held against excessive up;

the intermediate strip. It is thus seen that.

the top 10 may be moved upwardly until the cross plate 15 engages the under side of the stationary strip 7.

As illustrated particularly in Figure 1 a pair of extension leaves 20 may be posi-.

tioned beneath the main top 10 and on opposite sides of the strip 7.. The extension leaves 20 are preferably of the same thickness as the stationary intermediatestrip so that the top 10 will flatly rest on the intermediate strip and the extension leaves. Further when in the position illustrated in Fig. 1 the outer edges of the extension leaves 20 are flush with the outer edges of the top 10 whereby to present a neat appearance- Y The extension leaves 20 are rigidly con nected to pairs of supporting arms 28 the said supporting arms being secured to the undersides of the leaves'and extending r'or a substantial distance beyond the inner longitudinal edges of the same. FigureQ illustrates that the supporting arms 28 are slidable through openings 29 in the cross bars (Sand that the armsare gradually increased in thickness toward their inner ends so that as the leaves are withdrawn or moved edges of the cross bars 6 and the supporting arms 28 have engagement with the bottom walls of the openings soithat as the leaves 20 are moved outwardlythe top as well as the leaves will be moved upwardly. However, when theleaves 2O are'movedbeyqnd I the top 10 the top drops down flush with the extension leaves. The inner portions of the arms are confined between the inner edges of the bracket 8 and between guide strips or lugs 35 so that the arms are held against lateral movement. Figure 3 illus trates that the bracketsfi not only connect the intermediate strip 'i's to: the table but also" form guides for the arms 28.

The outward movement of the leaves2Ois linesin Figure lwhereuponthetop 10 will) drop and assumea position flush with the leaves. lVhenextended the leavesarese curely supported by means or" the arms 28- which of course remain inengagement with the intermediate strip 7'. When ll'i'lS desired to return the leaves" to the fullline-- position as illustrated? in Figure 1' it" is merely necessary to movethe" top 10 upwardly and slide. the leaves inwardly;

As illustrated in. Figures 2 and 3" the brackets Shavea holding strip 6O connected thereto, the J said holding strip forming a means to secure the arms in position. That is'to say tl'ieholdingstrip limits the downward movement of the arms-28.

Having thus. described the invention, what I claim is l. A tablelcomprising cross bars, a stationary strip permanently secured to said cross bars and having its longitudinal edge portions cut away to. define shoulders, a movable top having its under side provided with parallel guide strips received'insaie cutra-way portions, the. ends of said guide strips being; adapted, to engage said shoulders whereby to hold the top. against endwise movement, and a. cross plate secured to said guide strips and adapted to contact-with the under side of'said stationary strip.
